摘　　要：目的:探究下颌阻生智齿冠周组织病理改变的影响因素。方法:回顾垂直及远中阻生下颌智齿拔除时行冠周组织病理学检查的79例患者的临床病理资料,分析病理改变的影响因素。结果:根据病理诊断分为囊性改变组68例、牙龈瘤组10例、牙龈癌1例。囊性改变中的鳞状上皮增生活跃组年龄显著大于不活跃组(P=0.032)。曲面断层上透射影的大小与上皮增生是否活跃无明显相关(P=0.787)。远中透射影比透射影包绕整个牙冠的病例上皮增生更为活跃(P<0.001)。A类阻生牙囊性变的上皮增生比例更高(P=0.012)。结论:年龄增加、A类阻生及远中透射影提示下颌阻生智齿冠周组织的上皮增生可能更活跃,建议尽早拔除智齿后冠周组织行病理学检查。Objective:To explore the influence factors of histopathological changes in the pericoronal tissue of impacted mandibular wisdom teeth.Methods:The clinical and pericoronal tissue histopathological features of 79 patients with vertical and distal impacted mandibular wisdom teeth were reviewed, and the influencing factors of histopathological changes were analyzed.Results:According to pathological manifestations, all cases were divided into cystic change group of 68 cases, epulis group of 10 cases and gingival carcinoma of 1 cases.The age of the active squamous hyperplasia group was significantly higher than that of the inactive group(P=0.032).There was no significant correlation between the size of the pericoronal radiolucency and the activity of epithelial hyperplasia(P=0.787).Epithelial hyperplasia was more active in patients with distal radiolucency than in those with radiolucency surrounding the entire crown(P<0.001).The active hyperplasia was more common in Class A impacted teeth(P=0.012).Conclusion:The increasing of age, Class A impacted teeth and distal radiolucency increased the activity of epithelial hyperplasia of pericoronal tissues.It is recommended to conduct pathological examination of pericoronal tissues after removal of impacted mandibular wisdom teeth.
